How to Enable 4/ 5/ 5.1 Speakers
You have to activate the "Mixer" program and enable the
"4-Speaker", "5 Speakers", or "5.1 Speakers" mode to let the
audio driver recognize your rear or center/subwoofer speakers,
and have the front/rear/center/subwoofer speakers work. The
audio driver will activate the audio chip to output different
sounds from the front/rear/center/subwoofer speakers based
on different playback formats. For more information, please
refer to the 5.1.5 Mixer Advanced-Speakers dialog.
How to Adjust the Microphone Volume
You have to use the microphone when availing yourself of the
"Echo" function. If the microphone is on and is very close to the
speakers, it will cause feedback between the two. Also,
unusual high frequencies or buzzing sounds might be heard
from the speakers.
To avoid this, you have to adjust the
microphone
volume
in
both
recording
and
playback.
Sometimes you might have to adjust the main and Wave
volume as well. Please left-click the mouse to adjust the
microphone(MIC) in both Volume and Recording Control.
